The existing Wastewater Treatment Facility for the Village of Holmen was originally constructed in 1982 and was badly in need of repair and upgrades to keep up with the village’s population growth, as well as to meet more stringent environmental limitations. It was determined that a new Headworks Building, Oxidation Ditch, Blower Building, Sludge Dewatering Building, and Tertiary Filter Building would be constructed. The project also included renovations to the existing Clarifiers and Admin/UV Treatment Building.
KFI provided mechanical and plumbing engineering design to support the renovation of the Admin/UV Treatment Building and construction of the Headworks, Blower, Sludge Dewatering, and Tertiary Filter Buildings. Consideration was required for the upfront cost and the longevity of mechanical systems given the harsh environments in wastewater treatment facilities. KFI designed ventilation systems to minimize corrosion and ensure operator safety in the plant. An effluent water reuse system was also designed to allow the plant to use the treated wastewater for non-potable water needs throughout the plant. This system will reduce the operating cost of the plant by minimizing the need for municipal supply of non-potable water.
The plant is fully operational and treating all wastewater for the Village.
